Head pose tracking system

摘要

Video images representative of a conferee's head are received and evaluated with respect to a reference model to monitor a head position of the conferee. A personalized face model of the conferee is captured to track head position of the conferee. In a stereo implementation, first and second video images representative of a first conferee taken from different views are concurrently captured. A bead position of the first conferee is tracked from the first and second video images. The tracking of head-position through a personalized model-based approach can be used in a number of applications such as human-computer interaction and eye-gaze correction for video conferencing.
